Description

FIELD OF THE INVENTION

This invention relates to a new Bacillus coagulans strain, which alone or in combination with other Bacilli strains can be used as probiotics or together with a prebiotic and a symbiotic. The invention also relates to a composition such as a pharmaceutical composition, dairy product, functional food, nutraceutical, dietary supplement, and product for personal care comprising the new Bacillus coagulans strain alone or in combination with other strains, as well as use of the strain for prevention or treatment gastrointestinal infections and diseases, and other uses.

BACKGROUND OF THE INVENTION

Probiotics are live microorganisms or microbial mixtures administered to improve the patient's microbial balance, particularly the environment of the respiratory and gastrointestinal tract. Bacillus strains have been employed for the treatment of respiratory infections, prevention of diarrhoea, as well as, for the treatment of immuno-related diseases (Elshaghabee et al., 2017).
The normal intestinal flora is dominated by various bacterial species, which produce substances that help control the growth of pathogens. Dysbiosis is a condition that is characterized by a decrease of the certain bacterial species and an increased growth of pathogenic bacteria. Dysbiosis has been associated with the development of periodontal disease, inflammatory bowel disease, and chronic fatigue syndrome. Some studies have suggested patients with dysbiosis may have an increased risk of developing metabolic and cardiac disorders (Chan et al., 2013).
By administering probiotic Bacilli, it is possible to regenerate the intestinal flora of men and women with recurrent episodes of dysbiosis. Dysbiosis is a common gastrointestinal problem. Dysbiosis caused by Escherichia coli is also a common problem (Chan et al., 2013).
The presence of Bacilli is important for the maintenance of the intestinal microbial ecosystem. Bacilli have been shown to possess inhibitory activity toward the growth of pathogenic bacteria such as Listeria monocytogenes, Escherichia coli, Salmonella spp. and others (Yilmaz et al., 2005). This inhibition could be due to the production of inhibitory compounds such as organic acids, hydrogen peroxide, bacteriocins or reuterin or to competitive adhesion to the epithelium (Abriouel et al., 2010).
Bacilli have also been examined as a treatment of respiratory tract infections (Marseglia et al., 2007). For example, the installation of Bacilli, and stimulation of indigenous organisms has been employed to prevent recurrence of urinary tract infections (Marseglia et al., 2007). The role of Bacilli in preventing intestinal infections has also been investigated.

DESCRIPTION OF RELATED ART

The importance of Bacilli as probiotics has been described in the literature.
Hyronimus et al., 2000 discloses the screening of probiotic activities of a number of Bacilli strains by in vitro techniques and evaluation of the colonization ability of thirteen selected strains in humans. The strains were examined for resistance to pH 2.5 and 0.3% Oxgall adhesion to Caco-2 cells and antimicrobial activities against enteric pathogenic bacteria (Khochamit et al., 2015). Bacilli have been shown to possess the primary requirement of GIT stress tolerance, besides having good adhesion and bio-therapeutic properties (Thakur et al., 2016).
Pharmaceutical compositions of Bacilli known in the art are not sufficiently efficient in recolonizing in vivo i.e., mammalian microbial ecosystems and there is, therefore, a need to find Bacilli with an inherent ability to recolonize upon administering the Bacilli in the form of a pharmaceutical composition, a nutraceutical, a dairy product, a functional food or absorbent product. Bacilli isolated from soil, may have the ability to recolonize in vivo upon administration because of their inherent ability to survive in the human microbial ecosystem. It is often a cumbersome process to identify Bacilli strains with enhanced abilities to colonize upon administration and it is therefore important to select the best test systems to predict their in vivo ability to colonize.
In the literature, there seems to be a large variation in the reported in vitro adherence of probiotic strains. This variation indeed reflects biological differences between strains, but certainly also depends on experimental conditions. Moreover, there also seems to be variation with regard to how to measure the adherence. It may be argued that an in vitro experiment only serves as a means to estimate the in vivo ability to colonize by adherence to epithelial cells.
Despite being long considered soil microorganisms, Bacillus spp. have been used for more than 50 years in the form of fermentation products or spore-based supplements (Cutting et al., 2011). Bacilli, being ubiquitous in nature, consistently enter the gastrointestinal and respiratory tracts of healthy people through food, water, and air (Benno & Mitsuoka, 1986). They have been isolated from the gut and can reach up to 10⁷CFU/g and hence are considered to be one of the dominant components of the normal gut microbiota (Lakshmi et al., 2017). More recently, strains of Bacillus clausii have been isolated in order to provide more specific functions and its safety has been evaluated. Bacillus clausii has been previously used in diarrhoeal patients (Sudha et al., 2013, Horosheva et al., 2014) and children with recurrent respiratory infections (Marseglia et al., 2007) with no adverse events reported. Though the countries and strains are not specified, Bacillus clausii has been commercialized in 55 countries around the world (Nista et al. 2004; Gabrielli et al. 2009). The literature review for Bacillus clausii showed no adverse events related to the probiotic and the worldwide presence of bacteria in different countries supplements the narrative of its safety for human consumption.
Bacillus coagulans has a long history of use in a variety of foods. There have been many strains of Bacillus coagulans that have been widely consumed around the world for decades (Endres et al., 2009). The presence of this bacterium can be found in foods such as yogurts, milk, sauerkraut, kimchi, and other dairy products, all of which contain levels of Bacillus coagulans from 5×10⁹CFU/g (Sudha et al., 2016) to 9.38×10¹⁰(Endres et al., 2011). Several Bacillus species have been reported to be common in honeys and include Bacillus megaterium, Bacillus coagulans, Bacillus subtilis, Bacillus licheniformis, and Bacillus pumilus (Alippi, 1995; Alippi et al., 2004; Gilliam, 1979; Gilliam & Valentine, 1976; Snowdon & Cliver, 1996). The origin of this bacterial species for use in probiotics stems from India, where a number of manufacturers produce Bacillus coagulans as a food ingredient for export and relabeling in Europe and the US (Cutting, 2011). In order to assess the safety of Bacillus coagulans, the genome was investigated and it was found that it did not contain any deleterious genes (Salvetti et al., 2016). Due to the nonhazardous nature of Bacillus coagulans, this bacterium has been reported safe by the US Food and Drug Administration (FDA) and the European Union Food Safety Authority (EFSA) and is on the Generally Recognized as Safe (GRAS) and Qualified Presumption of Safety (QPS) list (European Food Safety Authority, 2017). Some of the non-pathogenic strains among the 100 known Bacillus spp., including Bacillus coagulans and Bacillus subtilis, were stated as safe for human consumption for all ages (Nithya & Halami, 2012). A literature review for Bacillus coagulans shows no adverse events related to the probiotic which solidifies the findings that is well tolerated and safe. Therefore, Bacillus coagulans may be considered a probiotic of safe and consumption providing benefit to the host.
Bacillus megaterium has been found on diverse habitats from soil to seawater, sediment, rice paddies, honey, fish, milk and dried foods (Alfoldi, 1957; Alippi & Reynaldi, 2006; Padgham and Sikora, 2007; Pelletier & Sygusch, 1990; Vary et al., 2007; Von Tersch and Carlton, 1983; Scholle et al., 2003, Kotb, 2014). Further qualitative analysis of microorganisms isolated from honeys revealed that one of the most frequent species of Bacillus is Bacillus megaterium (Alippi, 1995; Alippi et al., 2004; Snowdon & Cliver, 1996; Tysset, Durand, & Taliergio, 1970). There have been supplemental studies that have isolated Bacillus megaterium in fish (Sumathi et al., 2017). Afrilasari et al., 2015 also successfully isolated Bacillus megaterium from catfish digestive tract and identified the strain as PTB 1.4. The nonhazardous nature of Bacillus megaterium has landed the bacteria on the Qualified Presumption of Safety (QPS) list (European Food Safety Authority, 2017). Bacillus megaterium strain ATCC 14581 has been confirmed through genome-analysis to be nearly identical (>99%) to Bacillus megaterium MIT411. Health Canada stated the organism is not hazardous to human health or the environment; and exposure to the environment and Canadians is medium. Therefore, it is concluded that Bacillus megaterium strain ATCC 14581 is not harmful to human health or to the environment (Health Canada, 2018).
In summary, Bacilli strains with probiotic capabilities should be able to adhere to other suitable cells, such as the cell line Caco-2 cells. Moreover, it is also desirable that the Bacilli strains with probiotic capabilities show in vitro inhibitory activity against other bacterial species, produce acid after growth in liquid culture and/or produce hydrogen peroxide.

DETAILED DESCRIPTION OF THE INVENTION

Genotypic Identification

The Applicant collaborated with Cornell University (Ithaca NY, USA) for genomic sequencing and identification.

WGS DNA Composition

The whole genome sequence (WGS) was carried out by Cornell University, including assembly and annotation. Bioinformatics analysis was completed at Cornell University and at Deerlands Probiotics and Enzymes (Kennesaw, GA, USA). Identifying gyrB gene poymorphism was carried out the the Applicant.
The gyrB gene encodes DNA gyrase subunit B. DNA gyrase negatively supercoils closed circular double-stranded DNA in an ATP-dependent manner to maintain chromosomes in an underwound state. Gene sequencing analysis used the gyrB gene polymorphism, a well-established method for species level discrimination of prokaryotes (Bavykin et al., 2014; Wang et al., 2007). The representative genomes ere reviewed and curated by NCBI, and coordinated with the UniProtein Consortium (NCBI, 2016; UniProt, 2016). R package SequinR coupled with the UniProt Consortium analysis was used to compare whole genome sequences (WGS) and GyrB sequence of the presently claimed Bacillus coagulans strain CGI314 with other reference strains (Tables 1 to 3 below)
Genotypic, gyrB, & 16S rRNA Identification of Bacillus coagulans CGI314
CGI314 was isolated, and the genome was considered successful.
The genome size (3.0 Mbp) of CGI314 was shorter than that of previously sequenced B. coagulans strain (3.4 Mbp) (Upadrasta et al., 2016). The % GC (47.3%) is consistent with that of a previously sequenced B. coagulans strain (46.5%) (Upadrasta et al., 2016).

16S rRNA

Whole genome sequencing (WGS) and 16S rRNA analysis of CGI314, as compared to the four reference strains, exhibited an average nucleotide identity (ANI) score for 16S rRNA of 99.9% when compared to the B. coagulans strain ATCC 7050. The genome size (3.0 Mbp) and GC content (47.30%) for CGI314 was comparable to the four reference strains.

Further Deposits and Accession Numbers

Genome sequence data of Bacillus coagulans strain CGI314 (Fortispore) was deposited into NCBI GenBank database, and the genome sequence was annotated with the NCBI Prokaryotic Genome Annotation Pipeline (PGAP). The genome is publicly available, with GenBank Accession Number JABBFU000000000.1 for the strain, and available for instance at the link: https://www.ncbi.nlm.nih.gov/nuccore/JABBFU000000000.1.
Genome sequence data of Bacillus clausii strain CSI08 (Munispore) was deposited into NCBI GenBank database, and the genome sequence was annotated with the NCBI Prokaryotic Genome Annotation Pipeline (PGAP). The genome is publicly available, with GenBank Accession Number JABBNL000000000.1 for the strain, and available for instance at the link: Alkalihalobacillus clausii strain CSI08, whole genome shotgun sequenci—Nucleotide—NCBI (nih.gov).
Genome sequence data of Bacillus megaterium strain MIT411 (Renuspore) was deposited into NCBI GenBank database, and the genome sequence was annotated with the NCBI Prokaryotic Genome Annotation Pipeline (PGAP). The genome is publicly available, with GenBank Accession Number JABBNK000000000.1 for the strain, and available for instance at the link: Priestia megaterium strain MIT411, whole genome shotgun sequencing pro—Nucleotide—NCBI (nih.gov).
Phylogenetic Placement, carried out by Deerland Probiotics and Enzymes, Inc.
Genome-to-genome distance calculation (GGDC), a digital gold standard, is as reliable as DNA-DNA hybridization (DDH) (Auch et al. 2010). GGDC holds more discriminatory power for subspecies delineation and subsequently, was used as a confirmation of multiple alignment and phylogenetic analyses. GGDC yielded calculation-based models that further verified that Bacillus coagulans CGI314 is a close relative to ATCC 7050.
Although the conserved 16S rRNA sequence is a well-established method to compare and study phylogenies in bacteria, the high proportion of sequence similarity between closely related species limits its usefulness (Wang et al., 2007). High rates of 16S rRNA sequence similarity in closely related bacterial species are due to a slower rate of molecular evolution. Past research (Bavtlin et al., 2004; Wang et al., 2007) supports the validity of using gyrB sequences as taxomonic biomarkers due to their rate of base substitutions and significant and reliable correlation with DNA-DNA Hybridization analysis (Dauga et al., 2002; Kasai et al., 1998; Wang et al., 2007). The gyrB encodes DNA gyrase B, and type II topoisomerase that plays an important role in DNA replication. Gyrase B subunits are encoded by the gyrB gene.
Phylogenetic analysis using neighbor-joining (NJ) method (Saitou & Nei, 1987) placed Bacillus coagulans CGI314 in a clade with Bacillus coagulans ATCC 7050 (FIG. 2 ). This confirms all previous genomic identity determinations. Bacillus coagulans CGI314 has been placed in the Bacillus coagulans group.

These data suggest that Fortispore could help digest these compounds in the gut.
Fortispore has esterase, peptidase, phosphatase and glucosidase activity:
Fortispore was positive for esterase, peptidase, phosphatase, and galactosidase activity using API ZYM kit which implies:

- a high possibility of Fortispore to generate free fatty acids from the action of esterase in the presence of an appropriate lipid source.
- Galctosidase adds to the carbohydrate catabolism potential of Fortispore as these are active against various oligosaccharides, lactosylceramides, lactose, and numerous glycoproteins.
- Aminopeptidases which catalyze the hydrolysis of leucine, valine and cysteine substrates.

Indeed, in silico analysis have identified genes encoding esterases, peptidases, and galactosidases.

Fortispore releases free amino acids from glycolysis and protease metabolism
Metabolomic analysis reveals Fortispore fermentation and proteolytic capability towards milk carbohydrates and proteins generating a range of amino acids.
UHT Milk model was used to analyse the carbohydrate fermentation and proteolytic abilities of Fortispore. GC-MS analysis identified a total of 38 free amino acids (FAA) compounds, of which 10 were found to be statistically significant in Fortispore. A few of the carboxylic acids identified are associated with carbohydrate metabolism pathway, which confirms the presence of a Lactose/galactose/glucose uptake and enzymatic metabolism system to be active in Fortispore. Additionally, there is also evidence of an active proteolytic system in Fortispore as there is a release of a few amino acid linked with peptidase activity and benzoic acid which is linked with further catabolism of phenylalanine.

TABLE 13

Overall, the enzymatic and metabolomic data suggest that Fortispore has active carbohydrate-metabolizing enzymes, as most of the compounds generated are those from the glycolysis pathway (conversion of carbohydrates in milk). Additionally, there is evidence of potentially active aminopeptidases, lyases and decarboxylases generating carboxylic acids and releasing amino acids from Fortispore fermented UHT milk.

Fortispore is slightly more efficient in producing compounds beneficial in skin health in comparison to competitor B. coagulans strains
Ganeden Biotech markets B. coagulans 6086 (BC30™) as an anti-aging probiotic,as it produces maximum amounts of naturally derived L+ lactic acid, bacteriocins, hydrogen peroxide, enzymes and other metabolites. Lactic acid is associated with anti-aging, fighting acne due to its antimicrobial activity and hydration. Succinic acid is also associated with anti-inflammatory, antimicrobial and hydration. Benzoic acid is associated with anti-microbial activity.
FIG. 22 compares Fortispore with Lactospore and BC30 in the production of lactic acid, succinic acid and Benzoic acid. Significance is indicated by a, b and/or c, multiple letters indicate results are not significantly different from more than one group (PC 0.05). Error bars present standard deviations.
Our results show Fortispore to be slightly more efficient than BC30™ in terms of lactic acid production and superior in succinic acid and benzoic acid production.
Fortispore can produce amino acids beneficial in skin health in comparison to competitor B. coagulans strains
Fortispore is compared with Lactospore® and BC30. Our results show Fortispore to be superior to BC30™ and Lactospore® in producing methionine, proline, lysine and tryptophan.
Methionine is a sulfur-containing amino acid that improves the tone and elasticity of the skin, promotes healthy hair and strengthens the nails. Proline helps lower inflammation, which promotes a healthy immune system. It also helps trigger a cascade of anti-inflammatory compounds and genes that help with recovery. Lysine is an essential amino acid with many benefits that range from preventing cold sores to reducing anxiety and promoting wound healing. Tryptophan is associated with relief from depression and anxiety.
FIG. 23 compares Fortispore with Lactospore and BC30 in the production of amino acids. Significance is indicated by a, b and/or c, multiple letters indicate results are not significantly different from more than one group (P<0.05). Error bars present standard deviations.
Fortispore proteomics analysis identifies proteins with potential probiotic benefits
Extracellular secretions of Fortispore were sent to mass spectrometry to identify proteins released by the probiotic strain. A total of 28 proteins were detected of which 6 had potential probiotic benefits.

Assess Adhesion Ability to an In Vitro Model of Intestinal Epithelium

Cell lines: Human Colorectal Adenocarcinoma Cell Line HT-29 and mucous-secreting cell line HT-29-MTX were propagated using low glucose DMEM medium supplemented with 10% Fetal Bovine Serum, 2 mM glutamine, 100 U/ml penicillin, 100 μg/l streptomycin, and 2 μg/ml amphotericin B in a 5% CO₂atmosphere at 37° C.
Cells were seeded onto 24-well plates at a density 5×10⁵cell/well and cultured for 21-28 days to complete maturation. Media was replaced every 2-3 days.
Prior to experiments cells were washed twice with 0.5 ml DPBS. DPBS was completely aspirated from the wells after the second round of washing.
Preparation of spores: Ten milligrams of B. clausii CSI08, B. megaterium MIT411 and B. coagulans CGI314 spores powders were weighted in 15 ml falcon tubes and resuspended in 10 ml of full culture medium without antibiotics. Suspensions were aliquoted and stored at −20° C. until use. Suspensions were used within 2 weeks upon preparation.
Adhesion assay: 500 μl of spores suspensions (1.3×10⁷-9.2×10⁷CFU/ml) were added to HT-29 and HT-29-MTX cells, mixed by a gentle swirl, and incubated for 2.5 h at 37° C. in the CO₂incubator. Control wells not containing mammalian cells were prepared and incubated in parallel in the same way (0.5 ml of spores' suspensions).
Upon incubation HT-29 and HT-29-MTX cells were washed 4 times with 0.5 ml PBS. After that 50 μl of Trypsin/EDTA solution and 50 μl of PBS were added to the wells and incubated for 10 min with gentle shaking (˜100 rpm) at 37° C. Fifty microliters of Trypsin/EDTA solution were added to control wells.
Consequently, 450 μl of PBS were added to the wells with spores, contents of the wells were transferred into Eppendorf tubes with scrapping and subjected to three rounds of vigorous shaking 30 sec each. Contents of control wells were transferred into Eppendorf tubes and subjected to one round of shaking.
Serial dilutions (plus dilutions of control wells) were prepared in PBS and plated onto BC agar (B. coagulans CGI314) or PetriFilm™ (B. clausii CSI08, B. megaterium MIT411). Plates were incubated at 37° C. for 48 h prior to counting, PetriFilm were incubated at 37° C. for 24 h prior to counting.
Experiments were performed two or three times with three technical replicates per experiment. The results are expressed as means±SEM.

Conclusion

- 1. Results set out above demonstrate higher ability of spores to adhere to the mucous-secreting cell line HT-29-MTX compared to non-mucus secreting cells, possibly due to spores' physical properties.
- 2. B. megaterium MIT411 and B. coagulans CGI314 spores have higher (but overall low) ability to adhere to non-mucus producing cell line HT-29 compared to B. clausii CSI08 spores.

Study Description

Healthy adults aged 18-65 years were recruited and screened for participation in the study. Eligible participants were randomized 1:1:1: to either one of the two experimental groups or control group and underwent 45 days of treatment and 2 weeks of follow-up to evaluate safety and efficacy of new probiotic strains in healthy adults.
For the purpose of this investigational products were packed in individual capsules, that corresponded to the daily dose. Each capsule contained 300 mg of ingredients:

- Probiotic formula 1: Bacillus coagulans CGI314 and Bacillus subtilis DE11® (1×10⁹CFU total), ˜4.17 mg; Low Moisture Rice Maltodextrin, 292.23 mg; Medium Chain Triglycerides, 3.6 mg.
- Probiotic cocktail: 2×10⁹CFU Bacillus spores, including Bacillus subtilis DE111® (about (and greater than) 0.5×10⁹CFU), 2.1 mg; Bacillus megaterium MIT411 (about 0.5×10⁹CFU), 2.1 mg; Bacillus clausii CSI08 (about 0.5×10⁹CFU), 2.1 mg; Bacillus coagulans CGI314 (about (and less than) 0.5×10⁹CFU), 2.1 mg; Low Moisture Rice Maltodextrin, 288 mg; Medium Chain Triglycerides, 3.6 mg.
- Placebo consisted of all the same ingredients as investigational product only without probiotic organisms. Placebo was in individual capsules, that corresponded to the daily dose. Each capsule contained 300 mg of ingredients: Placebo: Low Moisture Rice Maltodextrin, 296.4 mg; Medium Chain Triglycerides, 3.6 mg.

Table 17 summarizes the change in scores of the Gut-brain axis questionnaire from baseline to the end of the treatment period, for the 4 probiotic groups and the placebo group. Mean changes with 95% confidence interval are shown. Results of the ANOVA omnibus test (p*-value) and one-sample T test (p-value) are also presented. Test of normality for the change in scores of the Gut-brain axis show that the data do not follow normal distribution, which could affect the results with borderline significance (p-values between 0.05 and 0.10). This affects two items: Loss of energy and Changes in appetite. An alternative nonparametric Kruskal Wallis test was applied to these items; p-values of 0.111 (Loss of energy) and 0.123 (Changes in appetite) were observed.
In general, mean values of the score changes of the Gut-brain axis questionnaire are negative for all the symptoms tested, meaning that the symptoms were less intense (participants were less bothered by these symptoms) at the end of the treatment period. One-sample T-test results show that in one third of tests (of 70 performed) a statistically significant change Gut-brain axis questionnaire score was observed. However, this can be observed for all treatment groups including the placebo group. Consequently, the results of the ANOVA test show, that no significant differences in Gut-brain axis score change among the treatment groups were detected, however a borderline significance for the items Loss of energy and Changes in appetite was observed. The participants in the Bacillus megaterium group experienced the largest change for these two items.

Kruskal-Wallis test did not show any significant differences in the number of days with clinically relevant infection treatment groups. However, a borderline statistically significant result was observed for clinically relevant gastrointestinal infection. This is probably due the fact that only no participants in the four probiotic treatment groups experienced clinically relevant gastrointestinal infection, while in probiotic group in total 2 days of such infection were observed, which could have happened by chance.
Nevertheless, compared to placebo, none of the study products containing probiotics showed a statistically significant difference.

A significant difference among groups was detected only in the number of days with constipation (p*=0.013) probably due the fact that only three participants in Placebo group had reported this symptom in Participant diary 2, while in other four treatment groups none of the participants had reported this symptom. However, further analysis (Mann-Whitney U test with Holm's correction) where number of days with constipation was compared between individual probiotic group and placebo group did not show significant differences, probably due to low sample size.

Efficacy Outcomes: Treatment Period

No significant differences in gastrointestinal health of the participants at baseline among the treatment groups were detected. Participants were randomized to 5 treatment group therefore such results were expected.
Scores of items in Gut-brain axis questionnaire were lower at the end of the treatment period compared to baseline scores, meaning that the participants were less bothered by these symptoms at the end of the treatment period. This can be observed for all treatment groups including the placebo group.
No significant differences in change (end of treatment period minus baseline) of Gut-brain axis item scores among the treatment groups were detected. Compared to placebo group, none of the study products containing probiotics showed a statistically significant difference Gut-brain axis score change.
No significant differences in improvement of Gut-brain axis item scores among the treatment groups were detected. Compared to placebo group, none of the study products containing probiotics showed a statistically significant difference Gut-brain axis score improvement.
No significant differences in sum of scores of all items in Gut brain axis questionnaire among treatment groups were detected. Compared to placebo, none of the study products containing probiotics showed a statistically significant difference in the sum of Gut-brain axis items scores at baseline or at the end of treatment period.
No significant differences in cholesterol and triglyceride changes (absolute and relative change from baseline to the end of the treatment period) among treatment groups were detected.
Compared to placebo, none of the study products containing probiotics showed a statistically significant difference in HDL, LDL, TC or TG change (absolute and relative) from baseline to the end of treatment period. The same findings were observed in the PP population.
Cytokine (TNFα, IFNα, IFNβ, IFNγ, and IL6) levels at the end of the treatment period were below the limit of quantification (LOQ) in all treatment groups. For cytokine IL13 some values above LOQ were reported, but no statistically significant difference between the treatment groups was observed.
No significant changes in heavy metals (Cadmium, Lead, Mercury, Copper, Nickel, Zinc, and Arsenic) levels at the end of the treatment period compared to the baseline values were detected in the Bacillus megaterium group. The same findings were observed in the PP population.
Compared to placebo, none of the study products containing probiotics showed a statistically significant difference in the number of days with symptoms of gastrointestinal infection. However, a borderline statistically significant result was observed for clinically relevant gastrointestinal infection. This is probably due the fact that only no participants in the four probiotic treatment groups experienced clinically relevant gastrointestinal infection, while in probiotic group in total 2 days of such infection were observed, which could have happened by chance.
Compared to placebo, none of the study products containing probiotics showed a statistically significant difference in the number of days with symptoms of respiratory tract infection. However, a statistically significant difference among treatment groups was detected in the number of days with runny nose—thick (p=0.018). probably due the fact that only three participants in Probiotic cocktail group have reported this symptom, while in other four treatment groups none of the participants have reported this symptom.
However, further post hoc analysis (pairwise comparison vs. placebo) did not show any significant differences.
Compared to placebo, none of the study products containing probiotics showed a statistically significant difference in the number of days with symptoms of urinary infection.
No statistically significant differences were detected among the treatment groups in stool regularity.
A significant difference among groups was detected for stool consistency, that is in the proportion of loose stools in the total treatment period as well as in weeks 6 and 7 of the treatment period. However, further post hoc analysis (pairwise comparison vs. placebo) did not show any significant differences, probably due to the low sample size. The participants in the Probiotic cocktail group had the smallest proportion of loose stool per all stools.

Efficacy Outcomes: Follow-Up Period

A significant difference among groups was detected only in the number of days with constipation (p=0.013). However, further post hoc analysis (pairwise comparison vs. placebo) did not show any significant differences, probably due to low sample size.
None of the study products containing probiotics showed a statistically significant difference in the number of days with respiratory tract infection symptoms.
None of the study products containing probiotics showed a statistically significant difference in the number of days with urinary tract infection symptoms.
No significant differences were detected among the treatment groups in stool regularity and stool consistency.

Safety Outcomes

In total 17 AEs were reported. Between 1 and 5 ADE were reported for each study product, most commonly gastroesophageal reflux (3 AEs), rash (2 AEs), and vertigo (2 AEs). No SAEs were reported.
Causality assessment revealed no relation between the reported AEs and the study products.
In summary, this study has addressed the safety and efficacy of new probiotics, namely Bacillus coagulans, Bacillus clausii, Bacillus megaterium and probiotic cocktail containing Bacillus subtilis, Bacillus megaterium, Bacillus clausii and Bacillus coagulans.
The gastrointestinal health of the participants at baseline among the treatment groups did not differ between the study groups, which was expected due to randomization.
The primary outcome of the study (safety) was achieved, as 17 AEs were reported in total with no SAEs. Causality assessment revealed no relation between the reported AEs and the study products.
None of the efficacy related outcomes showed any statistically significant difference, however this comes as no surprise due to small sample size per study group. Still, some trends favouring active products were observed, specifically in the Gut-brain axis scores and proportion of loose stools.
To conclude probiotic products showed to be safe to use in adults, and have shown some favourable trends regarding Gut-brain axis and stool consistency, however further studies with larger sample size, a run-in period to determine baseline stool consistency for each participant and use of validated questionnaires to determine the Gut-brain axis domains are needed in order to scientifically prove the efficacy of the studied products.
